' FRICTION DRAFT RlGGlNG FOR RAILWAY-CARS.

Specification of Letters Patent.

Patented Dec. 31, 1912.

Application filed May 28, 1909. Serial No. 498,824.

'To'aZZ whom it may concern:

occupy a small amount of space under thecare and at the same time will be convenicntl y accessible and easily put in.place on and removed from the car. v

To practically accomplish this object or result. and herein my invention consists, I combine with the draw-bar and draft yoke and draft members having front and rear stops or shoulders for the followers to abut against, a pair of wedge faced followers extending through the draft yoke, the front one abutting directly against the rear end ofthe draw-bar and the rear one abutting directly against the yoke or against the filler block at the rear end of the yoke, if the yoke is curved at itsrear end and a filler block employed therein, a pair of upper and lower friction blocks extending through the draft yoke and having inclined or wedging faces in frictional engagement with the inclined or wedge faces of the front and rear followers, the friction blocks having on their upper and lower faces recesses to receive and accommodate the upper and lower members of the draft yoke and permit the friction blocks to move to and from each other under action of the wedge faced followers, a vertically arranged spring and a pair of spring seats or bearing plates and connecting bolts extending between and connecting the lower spring seat with the upper friction block, the upper spring seat or bearing plate bearing against the lower face of the lower friction block. A removable tie plate extends dict-ween the draft members or draft sills and supports the rear end of the draft rigging. The filler block at the rear end of the draft yoke is furnished with supporting arms, one fitting on each side of the draft .y oke and resting upon the tie plate.

My invention also consists in the novel construction of parts and devices and in the novel combination of partsand devices herein shown and described and more particularly specified in the claim.

In the drawings, Figure 1 isa side elevation partly in longitudinal section of a.fricticn draft rigging embodying my invention; Fig. .2 is a plan view partly in horizontal section; Fig. 3 is a vertical cross section on line 33 of Fig.1; Fig. at is a horizontal sectioi on line 4-.4 of Fig. 1; Fig. 5 is a detail perspective view of the lower friction block; Fig. 6 is a detail perspective view of the filler block of the yoke.

In the drawing A represents the center or draft sills of the car to which the draft rigging is applied, A the front silliand A the carrier iron.

' B ist-he coupler draw-bar, B the draft yoke and B the filler block at the rear end of the draft-yoke, the same being preferably furnished with supporting arms I) which rest upon the removable tie plate U and thus support the rear end of the draft rigging.

D D are front and-rear draft members secured to the draft sills A in a suitable manner, as by rivets d.

F F are the followers, the front one abutting directly "against the rear .end of the draw-bar and the rear one abutting .directly against the draft yoke or the filler block B therein, if one is employed. The followers F F have each oppositely inclined or wedging faces f f, the portion of each follower upon which the wedge faces f f are formed, being preferably integral with ,the portion of the follower which engages the draft members D. The inclines of the front and rear followers face each other; that is to say, the inclines are on the adjacent faces of the followers.

G and G are upper and lower friction blocks extending through thedraft. yoke B and each having inclined or wedging faces 9 g engaging the corresponding inclines or wedging faces f of the follmversl. The upper friction block G has on its upper face a channel or recess to receive and arc unmodate the upper limb or member of the draft yoke and the lower friction block G has a corresponding ,but deeper recess or channel 9 on its lower face to receive and accommodate the lower limb or member of the draft yoke G and thus permit the upper and the lower friction blocks to separate or under action of the "hearing plate H being preferably interposed between the upper end of the springs and the lower friction block G pendingconnecting rods K extend through the -upper and lower friction blocks F F and the upper and lower spring seats or hearing plates H H at the ends thereof and fit astride the springs. These connecting rods or bolts K are provided withheads K at their upper ends andthreaded nuts K K and a cotter'K at their lower ends. As in my invention it is' only the wedge faced followers and upper andlower friction blocks which fit within the draft yoke and as the spring is an upright. or depending one arranged below .thedraft yoke, it will be readily seen bythose skilled in the art that my improved draft rigging isnotonly very short and compact but also very accessibleand capable of being easily and quickly removed and replaced and also of exceedingly simple construction and capable of being manufactured at small cost. 7 The shortness of my draft rigging adds greatly I Copies 0! this patent may be obtained for in -cents each, by addressing .the

The despecified.

to its strength and durability and the draft yoke is further strengthened by the drawbar followers and filler blockand by reason of the short space between the followers. The upright "spring is ordinarily arranged below the draft yoke and friction blocks, as illustrated. in the drawing and this is the preferred arrangement.

In a friction tion; a draw bar, bers; a pair of wedge faced followers e2- tending transversely through the r t he and engaging the draw bar and d ft v e upper and lower friction bloc is extending transversely through the draft yoke and having inclined friction faces cooperating with the inclined faces of the wedges; a vera. rigging, in con-wind tically arranged spring actingat. its inner draft yoke; draft men end against one of said friction blocks; connecting rods extending through said friction blocks and located on opposite-sides of the draft yoke; and a spring seat connected to said rods for the outer end of the spring to bear against, said rods removably connecting said blocks together, and the rods, friction blocks and spring seat removably encircling one arm of the yoke, substantially as CYRUS.
